About our trunks

Hey Alex, I Have Questions!

The Anti-Gravity Trunk is designed with a 2" inseam. The legs are designed to stay put, but can ride up a little depending on activities. The pouch is designed to be large enough to provide you room, while being double layered to also provide support and privacy for your privates. All of this is benefited by our use of MicroModal which is incredibly lightweight and breathable.

Our sizes run pretty true and the materials do have stretch to them.

But if you're not sure which size is going to be the best for you, consider these three things:

- Your waist in inches (pants size is OK).
- If your legs touch at the thighs.
- If you have a small, normal or large butt.

If your legs touch and your butt is large, you might jump a size.
If you have a small butt and thin legs, you can downsize.

In a word. Soft.

Really soft, our MicroModal is hand-selected to be of the highest grade available.

MicroModal is a modern technical fabric that is manufactured with cellulose from renewable Beechwood trees. Compared with Cotton, it's odor-resistant, 3 times softer, 50% more breathable, and it's not nearly as polluting or water-wasting.

Men come in all different shapes and sizes but for years underwear failed to respect our anatomy.

Our pouch is designed for the majority of men out there to accomodate and coddle. It's a blend of being soft with some stretch where needed, but also supportive for all day comfort. You won't need to adjust yourself anymore, because sticking to your legs is a thing of the past.

Please allow 2-4 days for processing, and the usual shipping times from the USPS: inside the US you can expect to see your package between 3-6 days. We'll send you a confirmation email with your tracking information as soon as it ships. If you have any questions or don't receive an email, feel free to reach out via our Contact Us Page.

Our number one goal is that you're happy with your purchase.

If something doesn't fit right, let us know and we will make it right.

Try on a pair and make sure it's perfect in you. If it doesn't work for you, your first pair is covered.

After this first pair, all underwear must be unworn, unwashed, in the original condition and packaging that you received them for a refund. If you bought a pack with multiple pairs, make sure you try ONLY one pair before you decide to use the rest.

Krakatoa is quite resistant to shrinking and fading, but machine-washing them in cold water using the delicate setting and drying in low heat will keep them looking fresher for longer.

Please do not bleach, iron, or dry clean your boxer briefs or trunks. You can also wash it by hand and lay it flat to dry, for great results.

We've built a tough product with reinforced stitching that lays flat and the very best materials we could get our hands on.

That said, you should follow the care instructions.

We provide a 52 Wash Guarantee which is triggered by either 52 washes or 12 months from the date of purchase. If your item has any structural damage before 52 washes or 12 months, we'll replace them for free.

Very comfortable underwear

Just bought a pair of trunks and got them the otherday. I absolutely love them, so soft and comfortable and the fly design is awesome. The material is what I was looking for. Thank you! P.S. Wish you had more color options. I will definitely be purchasing more in the near future.

Daily wear undies

I have been looking for underwear with the horizontal fly for a while. I came across Krakatoa and decided to give them a try. Once I received the first pair, I immediately ordered a few more. They feel amazing, have a roomy pouch, stay put and look great.

2 balls 1 pouch

Love them, very supportive so you can wear them when working out ie., running jumping. Easy access for when you need your junk out. Can’t say enough good things about them! Weird name, serious underwear!

New Favorite

Very comfortable. I really like the materials used. Have tried a few of the new “room for the boys” underwear and these are the best so far.

Get off the fence and buy them!

I saw an ad on Facebook for a trial pair of Krakatoa grundies, and remembered that my current family of underwear are now 20 years old. I've never been able to find any comfortable enough to replace my threadbare Hanes boxer briefs, not even their current stable of boxers. I wore my trial pair of Krakatoa briefs to work, and for the first hour, I was aware that something was different. Then, suddenly, they just disappeared. It was almost as if I was wearing nothing at all. I was so impressed after the first day, I immediately ordered a full set of briefs, and some trunks for those days when a shorter length is more appropriate. These are built tough, breathable, and have very easy access when you're in a hurry! I couldn't be happier with my purchase.

Good Pouch

Been searching for good underwear that provides a decent size pouch. Seems a no brainer, but harder to find than you would think.

2nd Order - I tested them and ordered more

The quality is exceptional and evident from the time you open the package. There is room for the boys to breathe. Comfortable is an understatement. If you're on the fence, TRY THEM!!! You won't be disappointed! If you have any questions, call or email them as their customer support is friendly, knowledgeable, and superb overall.

Love it

I never expected much of any underwear, to me they are just that, but from time to time when you wear something very uncomfortable you realize you need to pay attention to what protect your privates. This beauties works great. The 'extra' pouch is genial!! it keep my pride separated form the legs and the top opening is a game changer, who design the old awkward side opening for underwear?? This thing works great, pull down your zipper, grave it and get to business. It feel light and comfortable. Totally recommended. Size wise, I am 5' 8" 167Lb and the medium size seems a little large for me. but other than that, I will be buying more.

Very nice

I was happy using boxer briefs that I really liked for several years. They lasted so long that I had no reason to replace them. After several years of use, I decided to replace them and started researching for replacements since the originals were no longer available. After a few failed purchases, I tried Krakatoa. They arrived promptly and were an instant hit. They are very soft and stay supportive all day! My wife is very happy with how I look in them and cant keep her hands off me! She seems to appreciate the front opening even more than I do! I think I've found my new favorite brief.

New vibes

I really enjoy the fabric, cool against my skin, strechy in all the right places, and doesn't ride up where it shouldn't. I'm really looking forward to wearing these this summer.
